Maybe.. I centered the shock, had all bushings and washers in as seen in the pic.. and tightened the bolt as much as I could, guarantee more than 3 threads showing.

Like I said, as long as the washers and bushings were installed correctly and he tightened it good (which we verified), improper installation is pretty much out at this point; though to be fair it's asked because there have been a rash of guys who had the kits installed and the washers were not installed correctly (or at all). Defective shock is likely, as is an external force (which if the shock was defective it'd only prove that point).

Well, the Boss lift kit I looked at on toytec site now comes with rear bump stop extensions.
If you didn't receive or install them, you more than likely used the shock as the bump stop causing the damage.
The rear sway bar is thin and doesn't limit much flex, so even light wheeling can cause a full compression of the rear.
I would ask for a free shock to replace the damaged one, and get some rear bump extensions.
YMMV

Sent them an email, yesterday. Just waiting for the reply. Hopefully, I get a replacement. Are you or were you running extended bump stops?

That is odd, their older kits did not use a bump stop spacer... And I've installed a few kits and never seen one used or included besides LT setups.
But overall, it is a good sign. The superflex coils already offered quite a bit of travel. Hopefully the shocks in the kit now offer a bit more down travel also. I hate it that they don't give details on the compressed and extended lengths of the shocks... That's the info you really need to know.
Bump stop extensions do limit your up travel, but it is not a concern on a trail rig that does low speed stuff. In fact, I had some cheap shocks on my rig for a while that allowed me to run LT with no bump stop extensions. It resulted in really good articulation, but I often scraped my rear bumper corners climbing...The bump stops will help with articulated departure angles...
hmmm...these are interesting pictures. In my first response I indicated I think maybe you overcompressed the shock by not having extended bumpstops.
Not so sure after seeing that pic because it looks like the shaft had side to side movement that rubbed or damaged shaft (see those rusty areas) until the shaft was small enough diameter and it just snapped.
It reminds me of what happens when you repeatedly bend a piece of metal to get it to fatigue and break. Would definitely have the supplier take a look and weigh in on this one.
With regard to bumpstops, my opinion is that this is up to each person installing a lift to measure and modify as necessary. It may be that most don't find extended bumpstops necessary, but the correct way to determine is to remove the rear coil springs and compress the axle up to the existing bumpstop and then measure the distance from eye to eye of the shock mounts. If this amount of distance between the shock mounts is less than the shortest compressed length of the shock you are running, then you need to modify the length of the bumpstop so as not to overcompress. There are so many different suspension combinations, it is difficult for vendors providing lifts to predict the required changes to bumpstop length. And if they did, they would tend to be very conservative with the modifications to length (e.g. they will add an extra to ensure it doesnt over compress). This i why i think each owner is obligated to make measurements for themselves to ensure they dont overcompress the length of the shock. Now...is it a bit more difficult to do? Yes, and if the vendor doesn't provide the shortest compressed length for the shock it makes it very difficult to figure out how much more bumpstop length is needed (if any).
For example, lets say without the coil spring you push up the drivers side rear axle until it contacts the bumpstop and you then measure the distance from eye to eye of where the shock mounts and you find that distance to be 12.8", but you shortest compressed length of the shock (from eye to eye) is 14.0", then you need to add at least 1.2" to the bumpstop lenght.
Toyotas design is for the shock to be the down travel limiting factor. If the shocks are the incorrect length,have incorrect bushings with too small of a stud end/ cheap this would be the result . Compare that aftermarket shock with stock one on the stud end and compare, it's much smaller I bet. The factory Toyota one is very heavy duty large diameter and has a locating pin to keep the shock from moving around. That shock looks like a universal small stud (S1) which would not be correct for the rear of that Toyota.

Icon's like to snap off the bottom of the shaft

Just because you lift does not mean you need to extend the bumps. Only need to if you are running extended travel shocks. I have been running my lift for 5 years with stock bumps with no problems.
I guess you didnt see my post #33. The correct way is you need to measure and adjust the bumpstops accordingly (which may be that no changes are required or you need to extend them). This is not only true with extended travel shocks but with any change to the suspension be it shocks, lift, etc. Very few people do the measurements (including myself) and hope the aftermarket guys have taken this into account.
